Maybe we because we can observe these disasters happening in real time?
I find it absolutely wild that you can claim not to see climate disasters that are actively unfolding around us.
The first thing that really woke me up was the sudden loss of global sea ice in 2016. Take a look at the arctic death spiral if you aren't familiar already [0]. In 2012 if you mentioned that the response was "well yea but the antarctic is growing!!". There were good explanations for why that what happening during global warming, but that's no longer necessary since the antarctic is also declining rapidly [1].
Then there's lake Mead. I can't imagine you haven't been paying attention to what's happening there but we're on the path to reaching dead pool in a few years [2]. And yes, this is also due to poor resource management, but it is exacerbated by climate change and desertification of the region.
Then there's the amazon rain forest, which was once a carbon sink, becoming a net carbon emitter [3]
But the most important part of all of this, is that these events (which represent just a few examples of the impacts of climate changes) are not the new normal. Because the rate co2[4] and ch4[5] are being emitted is accelerating we're no where near a new stability point. All of the things we see now are just the beginning of a process that will only continue to accelerate each year for the rest of your life.
And that's just what we can observe and predict. Thwaites glacier, for example, will very likely collapse at some point in the next 100 years. We have no idea when, but when it does it will cause massive and near instant sea level rise. Far more concerning is that this tons of geological evidence that there are feed back triggers that cause rapid rise in GHGs and temperature and we don't know exactly when we might cross these. The book Under a Green Sky, by paleontologist Peter Ward lays out rather convincing evidence that the majority of extinction events have been caused by rapid climate change triggered by changes in CO2.
I'm not sure why you don't give these things more credibility.
